This is a number series based on a constant common difference: consecutive terms of the series differ by the same fixed value throughout, so the next term is obtained by applying that same fixed difference once more to the last given term.

1. First difference: 237 − 196 = 41.

2. Second difference: 196 − 155 = 41.

3. Third difference: 155 − 114 = 41.

4. Since every consecutive pair drops by exactly 41, the next term follows the same rule: 114 − 41 = 73.

Checking the completed series 237, 196, 155, 114, 73 confirms each term is exactly 41 less than the one before it, so the pattern holds consistently across all five terms.

Therefore, 73 correctly completes the series.
